Abstract
A cloud computing service to securely process queries on a database. A security device and method of operation are also disclosed. The security device may be provisioned with a private key of a subscriber to the cloud service and may have processing hardware that uses that key, sequestering the key and encryption processing in hardware that others, including operating personnel of the cloud service, cannot readily access. Processing within the security device may decrypt queries received from the subscriber and may encrypt responses for communication over a public network. The device may perform functions on clear text, thereby limiting the amount of clear text data processed on the cloud platform, while limiting bandwidth consumed in communicating with the subscriber. Such processing may include formatting data, including arguments in a query, in a security protocol used by the cloud platform.
